Chelsea defender Gary Cahill says the disappointment of their FA Cup humiliation is "unbelievable".
Chelsea were bundled out of the Cup at home by League OneBradford City.
Cahill said: "We were so disappointed with what happened on Saturday. It's unbelievable.
"It was a shock - maybe a wake-up call. We have a huge game that we have to go all-in in now.
"What will happen if we play the same way we played against Bradford? The obvious things that happen when you play like that against good teams.
"I don't think anyone has seen us play like that at Stamford Bridge for a long time. Who knows the reason behind it?
"It is the best thing now to be facing Liverpool in a game like this. We have obviously reflected on the Bradford game but we have to get that out of our system and be ready.
"It's a massive game - then we have Manchester City on Saturday, which is huge in terms of the League. So they are two games at Stamford Bridge, where we are usually very strong, that we need to bounce back in."
